  • Publication number: 20120016230
    Abstract: An imaging apparatus includes: a first illumination unit to apply visible light to a subject having a fluorescent substance; a second illumination unit to apply excitation light to the subject so that fluorescence is generated from the fluorescent substance; an optical filter unit to cause the visible light and the fluorescence to pass therethrough, and shield the excitation light; an imaging unit including imaging elements to generate image signals, and an output unit to read the image signals from the imaging elements and output image information; an optical element to divide the visible light into component light beams, cause the divided light beams to be incident on the imaging elements, and cause the fluorescence to be incident on at least one imaging element; and a control means for alternately applying the visible light and the excitation light and alternately outputting image information of the visible light and the fluorescence.

  • Patent number: 7859593
    Abstract: An imaging block includes a prism, first and second imaging devices, an analog/digital convertor, a timing generator, and first, second, third circuit boards. The prism separates light incident through a lens into at least two colors and outputs the light. The first and second imaging devices are each generates a video signal by photoelectrically converting the light. The analog/digital converter converts the video signal output from each of the devices into a digital signal. The timing generator generates a video-signal processing clock for driving the first imaging device, the second imaging device, and the analog/digital converter. The first imaging device is mounted on the first circuit board. The analog/digital converter and the timing generator are mounted on the second circuit board. The second imaging device is mounted on third circuit board and connected to both the first circuit board and the second circuit board through a cable.

  • Patent number: 7023772
    Abstract: At ST1, the process identifies whether apparatus identification information of an optical recording apparatus is recorded in an optical recording medium and, if it is not recorded, if the recorded information does not agree with apparatus identification information of the optical recording apparatus, or if they agree but information validation conditions are not met, it performs processing of ST2 and ST3 to perform power calibration processing of laser light and calculate power set values. At ST4, the process records power calibration information and the apparatus identification information in the recording medium. If the information agrees and the information validation conditions are met, the process performs processings of ST9 and ST10 to calculate power set values using already created information. At ST5, the process sets laser light power based on the power set values.
